Title: Manufacture of semiconductor device
Inventor: SHINOHARA KEIJI
IPC: H01L21/28
Filed: 1989-12-04
Abstract: PURPOSE:To form an opening part in an insulating film without damages such as irregularities in crystal lattices and contamination in a semiconductor substrate by forming a resist column on the semiconductor substrate, thereafter flattening the insulating film, embedding the resist column at the degree so that the head part of the column is exposed, an then removing the resist column. CONSTITUTION:A resist column 10 whose cross section is a rectangle or an inverted trapezoid is formed on a semiconductor substrate (Si) 1. Then, an insulating film 3 is flatly formed on the semiconductor substrate 1. The resist column 10 is embedded with the insulating film 3 by a degree so that the head part of the column is exposed. Then, the resist column 10 is removed. For example, a resist film 4A is formed on the semiconductor substrate 1 such as an Si substrate in which a diffused layer 2 is formed. The resist column 10 whose cross section is a rectangle is formed on the semiconductor substrate 1 by a photolithography technique. Then, the insulating film 3 is flatly formed on the semiconductor substrate 1, and the resist column 10 is embedded by a degree so that the head part of the column is exposed. Then, the resist column 10 is removed by ashing or dissolved and removed with organic solvent and the like. Thus a contact hole 6 is formed under the state wherein the diffused layer 2 is exposed from the insulating film 3.

Title: Dashpot
Inventor: HATSUDA TOSHIO
IPC: H01H33/42
Filed: 1997-11-17
Abstract: PROBLEM TO BE SOLVED: To shut electric current, without generating excess impact force by a circuit breaker for heavy current and high voltage, even in the case the electric current and voltage to be cut is low by installing a valve supported by a spring member installed in a cylinder or a piston and opened or closed by the pressure inside the cylinder, in a flow route hole formed in either the cylinder or the piston. SOLUTION: In addition to an oil flow route hole 3, a flow route hole 10 is formed in the wall face of a cylinder 2, and a valve 11 is installed in the hole 10 and the end part is fixed in a flat spring 12 fixed into he cylinder 2. In the case the electric current and voltage to be cut are high and the speed of the piston is low, the pressure rise in the inside of the cylinder 2 is low and the force affecting on the valve 11 is small, so that the flow route is kept open. On the other hand, when the current and the voltage to be cut at low and the speed of the piston is high, the pressure rise in the inside of the cylinder 2 is high and the valve 11 is closed, and consequently, the total flow route surface area becomes small, and the pressure of the inside of the cylinder is further increased. Consequently, since the impulse of the braking force can be increased when the piston speed is high, electric current can be shut, without generating the impact force.

IPC: B24B19/12
Filed: 1986-12-27
Abstract: PURPOSE:To lessen the number of times for work dimensional compensation at manual operation, by repeating two values of infeed to distribute at a rate to dressing frequency of a grindstone and an advancing figure of fraction value, and constituting it to perform the infeed of a wheel spindle head to dressing and truing so as to cause it to be reached to corrected compensation value of the grindstone. CONSTITUTION:Supposing that there is fraction value not to be divided at a minimum unit of an infeed rate of a wheel spindle head 6 by the infeed rate of the wheel spindle head 6 to dressing and truing per time in average, found by diving corrected compensation value R of a grindstone G by dressing frequency of the grindstone G. In this case, the infeed rate of the wheel spindle head 6 to stone correction value per time is set down to two values, the value omitting the fraction value and the valve raising it to a unit. And, both values of the said fraction value are repeated to distribute at a rate of dressing frequency N of the grindstone to an advancing figure of the said fraction value, whereby infeed of the wheel spindle head 6 to the dressing and truing, made so as to reach the corrected compensation value R of the grindstone is carried out. Therefore, the compensation value accords with a difference in less than 1/2 of the minimum feed unit by a servomotor 9 of the wheel spindle head 6 at all times.

Title: Polarization regression type photoelectric sensor
Inventor: MIYAZAKI MASAHARU
IPC: G01S17/88
Filed: 1992-11-25
Abstract: PURPOSE:To provide a polarization regression type photoelectric sensor using only one polarization filter. CONSTITUTION:A polarization filter 2 passing the polarized light in the preset vibration direction is fixed to a case 1 in front of a light projecting element and a light receiving element. A phase plate 3 generating the polarization constituent having the vibration direction perpendicular to the incidence light and the phase difference of 90 deg. is fixed to the case 1 via the polarization filter 2 between the light projecting element and the light receiving element. When the reflected light from a regression mirror rotating the vibration direction of the projected polarized light by 90 deg. passes through the phase plate 3, only the constituent in the polarization direction of the polarization filter 2 is intensified. When the reflected light from a mirror object not changed with the vibration direction of the projected polarized light passes through the phase plate 3, the constituent in the polarization direction of the polarization filter 2 is weakened.

Title: Pulse generation circuit
Inventor: UEDA HIDEAKI
IPC: F15B21/12
Filed: 1991-11-01
Abstract: PURPOSE:To output pulse signals of the same period by ensuring starting of pulse generation in order from a first output unit, at the time of re-starting, by outputting a fluid from each output unit while transmitting a signal for closing a fluid pressure operational valve of a previous output unit on one hand and transmitting a signal to a delay valve of a next output unit on the other. CONSTITUTION:It is ensured that pulse generation is re-started in order from a first output unit at the time of re-starting, and fluids are output from output units 7, 14, while one signal is transmitted as a fluid control signal for closing an air pressure operational valve of a previous output unit and the other signal is transmitted as a fluid signal to a delay valve of a next output unit, through opening/closing control channels 5, 11 as well as a fluid pressure signal channel 15. Time for fluid outputting of the output units 7, 14 can be adjusted as desired, while pulse signals of the same period can be output from the output units 7, 14 by the adjustment of delay valves 3, 10, or the pulse period can be changed. Pulses of the same period can thus be generated in order only by a mechanical structure.

Abstract: PROBLEM TO BE SOLVED: To avoid drop in transmission speed and to synchronize a phase and a frequency with firm and less energy consumption by transmitting a reference symbol for synchronism in a multi-point-to-point direction by a code different from that used for transmitting a data symbol. SOLUTION: In CDMA digital communication system, a reference symbol is spread in a multi-point-to-point direction, namely, with a code different from that used for transmitting data from a base station to plural mobile stations. The base station uses codes C1 and C2 for transmitting data and uses a different code C3 for transmitting the reference symbol for synchronism. It, is desirable that the reference symbol is transmitted over the whole length of a packet, namely, for length L2. Thus, synchronism which is difficult to be affected by interruption to phasing and transmission through a physical channel can be executed.
